Gigabyte GV-NX78T256V-B (NVIDIA 7800GT) Graphics card review @ OCW

OCW has posted a review on the Gigabyte GV-NX78T256V-B (NVIDIA 7800GT) Graphics card

The new GV-NX78T256V-B introduces an incredible 20 pixel pipeline in what is arguably the industry's powerful and technically advanced graphics accelerator card. The new high-end VGA card from GIGABYTE boasts NVIDIA's top-three mainstream architectures, the Power of 3, which comprise Shader Model 3.0, HDR (High dynamic-range), and SLI technology. GV-NX78T256V-B comes with 256MB DDR3 with GPU core running at 405MHz and memory at 1000MHz. How far can we overclock this card which is only 20 pixel pipeline. Will it be comparable to the more expensive 7800GTX card ?
